It’s official. Apple has sent out invites to a press event at 10 a.m. PT October 23 in the California Theater in San Jose. As usual, only a one line tease that said “We’ve got a little more to show you” was included on the invitation. Thanks to the never-ending deluge of Apple rumors that fly at us every day, we have some ideas of what the world’s most popular tech company might show. Current rumors point toward a new Mac minis, a 13-inch MacBook Pro with a Retina display, a curvy iMac, and an iPad Mini. From the looks of it, Apple may announce a number of smaller, ‘mini’ products at the event.

iPad Mini

The iPad Mini, or a smaller, 7.85-inch version of the iPad, has been rumored for months now. The rumors just don’t die. Most recently, a picture supposedly showing a list of iPad Minis that will possibly be stocked by German electronics retailer MediaMarkt has been leaked, complete with prices and basic specs. In addition to the usual 16, 32, and 64GB models, an 8GB iPad Mini may appear. Each version will have the choice of a black or white finish, and either Wi-Fi only or “cellular” and Wi-Fi.

The most basic 8GB Wi-Fi iPad Mini could be priced at 250 euros, and the top 64GB Wi-Fi with 3G or 4G at 650 euros. A quick currency conversion gives us $322 and $840 respectively, the latter of which will probably have seen wallets everywhere twitch nervously.

Just like all the other iPad Mini rumors, there’s no way to know if this is really a screenshot from MediaMarkt’s computer system, and equally we can’t take those prices as final either, as Apple’s U.S. pricing is often lower than it’s European equivalent.

iBooks 3 and education

We don’t have many details, but today Bloomberg reported that Apple will further emphasize education (and likely textbooks) when it introduces the smaller iPad. We don’t know what new features are shown, but a new version of iBooks is expected. Apple has deep roots in education and with the smaller iPad’s smaller price, it likely hopes to reach more classrooms.

New Mac Mini’s coming

Big fan of Apple’s tiny little Mac? You’re in luck. A new rumor from 9t05Mac points to new versions of the Mac mini rearing their adorable little heads at Apple’s rumored October 23rd event. Supposedly, the new Macs will come in two configurations, with varying memory and processor options as well as a third model for those who want to run OS X Server. Rumor has it that they’ll start shipping immediately after the announcement. Apple hasn’t updated the Mac mini in more than a year.

We assume that the new mini will get some form of visual refresh, but it’s hard to imagine Apple making it a whole lot smaller than it already is. Maybe a Mac micro?

13-inch MacBook Pro with Retina display

9to5Mac has also heard from a “consistently reliable source” that Apple will introduced a Retina display-equipped 13-inch MacBook Pro during the iPad Mini’s launch event later this month. It will apparently be thinner and lighter, and offer different combinations of processors and storage options too.

Macrumors.com has found a few potential features for the 13-inch Retina MacBook Pro on a Chinese website, which claims the smaller computer will still have two Thunderbolt ports, a USB port, a headphone socket, an HDMI-out and an SD card reader; just like its bigger brother. There’s also talk of an interesting battery design — although it’s not elaborated upon — and the report is accompanied by a couple of pictures that, frankly, could show absolutely anything.

Before we move on, it’s best to clarify that we’re talking about a product that doesn’t exist being launched at an event that hasn’t been announced for another non-existent product. That said, it’s logical for Apple to produce a 13-inch Retina MacBook Pro, but at the moment we don’t know when that will happen.

A curvy iMac

The curvy iMac rumors seems to originate from the same Chinese website, where it’s said that the new model will have a curved shell that’s something like “a water droplet,” which sounds more like Samsung’s design philosophy than Apple’s. Naturally, it too is going to arrive at the small “intimate” event set for October 23.
